I have been looking for a word that explains why I can talk to a 50 year old man, who presumably is wiser than me in the ways of life, politics and economics, but in three sentences I find him to not only be spectacularly ignorant about politics and economics, he is WEDDED to his ideology.
Facts I know to be true are dismissed by him.
The opportunity to look it up on the internet are rejected.
Logic I throw at him is ignored.
There is a pscyhological disease or disorder preventing that human's brain from being rational, logical and intellectually honest.
And I have found that term.
Your vocabulary word of the day is "Ego Investment."
I shall plagiarize it from The Rational Male henceforth.
